Welcome to PICU Doc on Call, the podcast where we break down real-life cases from the pediatric intensive care unit and share practical insights for clinicians everywhere! I’m Dr. Monica Gray, and I’m joined by my co-host, Dr. Pradip Kamat.

Today, we’re diving into a fascinating case: a 13-year-old boy who suddenly developed muscle weakness and was found to have severe hypokalemia. After some detective work, he was diagnosed with familial hypokalemic periodic paralysis, a rare but important condition to recognize in the PICU.

We’ll discuss the genetic underpinnings, classic clinical features, and common triggers associated with this disorder. Additionally, we’ll guide you through the differential diagnosis, key management strategies, such as potassium supplementation, and explain why genetic testing is so crucial. We’ll also cover essential considerations for anesthesia and cardiac monitoring in these patients.

Whether you’re a pediatric intensivist or just interested in acute neuromuscular care, stick around for some practical pearls you can use on your next shift!
